mufflers

[bigboremike]

hey everyone~
im just about to put my engine back in my car and get it back on the road for the summer, i did the whole 96mm P&C, 40 weber, 86a webcam etc...setup, and i wouldnt mind having it breathe really well and sound good too, any suggestions on exhaust (for sound and efficiency?)

You can't go wrong with a Bursch, since you live in a cold area (Illinois) I assume that you will keep the heat exchangers.

If you don't care or only drive the car in warm weather, get a Kerry Hunter Header.

I know alot of people here hate the Monza exhaust, but I like the way it looks. I'd agree with the headers, I have a simliar design. I live in MI, but don't drive in the cold.

Put Stainless exchangers and a Bursch on it
I was told by my mechanic that the stainless adds about 7hp, they scavange alot better than stock exchangers.

My car came with a Monza and I loved the way it looked, but it set off every car alarm in a parking garage . I replaced it with a Bursch system, quality was impressive and it carries a nice deep mellow tune.

If you really *have* to get the *most* out of the motor, you'll want to spring for the CFR headers. They're majorly expensive, at something near a grand a pop, but they are supposed to be the best for power.

Next best choice for power, and a lot lower priced, is the Kerry Hunter headers. He advertises in Panorama and possibly Excellence as well.

Muffler choices for either of those include Supertrapp, Flowmaster, or a generic "Turbo" muffler. I'm sure there are other options--since there is only one outlet from either, quite a number of mufflers will work.

After that, the SSIs and a Bursch should do OK. Plus you get to keep some semblance of heat.

Or, you could have a local shop make up a set of headers. The power gains will be pretty hit-or-miss. It depends on how well the shop knows what they're doing.

How good or bad is the OEM muffler????

I have a Stainles OEM Muffler and Stainles Heat Exchangers.......

Just wondering???

[Dave at Pelican Parts]

The OEM muffler is pretty good. It has a good mix of power and low noise. A stainless muffler is not really OEM--but it may be the same design.

Some people disagree, but the Bursch seems to be good for a little bit more power, and a good bit more noise.

I've read in many articles and have heard from many experts that the OEM muffler (at least for the 73-74 2.0) remains the best solution. It's essentially a motorsport design and has the best efficiency, not to mention looks original. Some of the aftermarket solutions look really out of place in my opinion.

I am putting a Sebring extractor on my 76 2.0 w/stock FI. The PO has switched the exchangers to stainless. This to me looked to be the closest to having a header type system while retaining the heat exchangers. I found it in Performance Products catalog.

[Dave at Pelican Parts]

You can also find them in the Pelican Parts on-line catalog. And for less than Performance Products sells them.

On my '75 2.0, I have the '73 - '74 2.0 stainless steel heat exchangers coupled with Bursh extractor/muffler.

Compared to the stock, convoluted and restrictive '75 system with catalyst, the power increase is significant. However, noise is also significant compared to stock, and I think the air pressure or frequency of the sound waves tends to set of car alarms much more readily than the stock muffler.

I was at an event last Saturday (Drive to Santa Cruz) and I had the opportunity to listen to a lot of 914's with both stock and modified exhausts. I think I like the stock sound, as it's a bit more "mechanical" and characteristic of what these cars are supposed to sound like. I would like to try a stock muffler on my car to see if it's indeed quieter. But I'm very happy with the performance of the SS/Bursch combo. Great throttle response and more grunt.

[campbellcj]

I have a Bursch on my 73 2.0 and I like the sound overall, but it is very different from stock. Louder yes, and also pretty "raspy" with quite a bit of barking on decel that is normally silenced by the stock mufflers on all 914s and 911s. A different note than an opened up / two pipe factory type muffler.

The build quality on Burschs is good but not fantastic. They are known for burning off their black paint in 2 days, after which they start to show rust unless you repaint them w/ high-temp paint. Some of the welds look pretty sloppy to me as well.

Anyway, I would recommend the Bursch as long as you don't mind a little extra noise. Can't comment on any power increase except that it couldn't possibly be more than a couple bhp if anything. All in all the Bursch is probably the best sounding & built muffler for the 914, except maybe the custom SS sport mufflers that cost 3-4x more.

Well I lucked up and bought a "used" Stainles
Bananna muffler. It came of a 73 2.0 that had been in an accident and the car burned, so I had to wash and clean it a bit. I installed it on my new 2.0, its sounds great. It has a mechanical sound to it as mentioned earlier, very indicative of these cars.....

I would suggest these mufflers to anyone wanting to quiet down their exhaust. I have had burshe, monza, and ansa. and they dont compare in quality of construction or sound.

Just my .02 cents....

If you want to be different, check out the custom exhaust that I used on the 914/6 3.0. I used two turbo mufflers that were welded together. They are tipped with two PowerTone muffler tips. The local shop did the bending and welding.

The bottom of the website shows the finished product. We did a 90 degree bend in toward the middle, crossed over and used two tips...
